A customer is writing critical data to the pre-configured, default NFS export on an EMC Data Domain system for
replication to a remote site. Which directory on the local Data Domain system should be reviewed to verify the
data is successfully being written?

Which CLI command will display information about disks in EMC Data Domain enclosures?

An EMC Data Domain customer wants to add a static route using the CLI. Which command is used?

When using VTL on an EMC Data Domain system, why should persistent binding be enabled on the host?

A customer notices an improved deduplication rate and write time into their EMC Data Domain system while
multiplexing is turned off. What is the reason?

NetBackup has been configured to use an EMC Data Domain appliance as a VTL for the primary target storage
unit. Which multiplexing setting should be configured within the NetBackup storage unit to achieve optimal
deduplication performance on the Data Domain?

A customer has EMC Data Domain system installed in their data center for two weeks. The environment
consists of the following.
1. Data Domain is configured as the primary backup device being shared by Avamar, NetBackup, Oracle
RMAN, and SQL Server backup clients
2. Avamar and NetBackup are using DD Boost to backup a total of 500 clients (250 each)
3. Avamar is configured to allow a maximum of 100 concurrent backups
4. NetBackup is configured to allow 150 concurrent backups writing to the Data Domain with the backup
window starting at 8 P.M. nightly
A total of 50 production Oracle servers are using NFS and 50 production SQL servers are using CIFS, each
performing full backups nightly between 11 P.M. and 5 A.M. The archive and transaction logs backs up every
15 minutes. The retention for all client backups is 30 days.
The backup administrators notice that between 8 P.M. and 11 P.M. every night, the Data Domain CPU is at
100% utilization. What is a potential reason for the high CPU utilization?

When implementing NFS with an EMC Data Domain system, why should hard mounts be used?

You are tasked with integrating two new EMC Data Domain systems into an existing EMC NetWorker
environment. Due to customer requirements, a VTL will be created on each Data Domain and drives will be
presented to each NetWorker storage node.
Which best practice should be provided to the customer for this configuration?

You are tasked with installing a new EMC Data Domain system in an existing NetWorker environment. The
customer requirements state that they need the ability to perform multiple concurrent clone operations from the
same device.
Which device type(s) supports the customer’s requirements?
